    Frequently Asked Questions (FAQ)

    Why does an induction furnace need a heating capacitor?

    During operation, induction furnaces produce reactive power to establish electromagnetic fields. An induction heating capacitor supplies this reactive power, optimizing the power factor and improving overall energy utilization efficiency.

    What are the available options for capacitor configurations?

    Configurations include pressure switches, internal discharge resistors, insulated or non-insulated cases, customized mounting fixtures, various cooling water connections, and customized terminal connections.

    What filling materials and dielectrics are used in Flair capacitors?

    We use all-film or metallized film as the dielectric, and non-PCB (polychlorodiphenyls) biodegradable insulation oil (such as PXE or M/DBT) as the filling material.

    What are the cooling water requirements for these capacitors?

    The system requires soft, impurity-free water with a pH value between 6 and 9. The inlet water temperature must not exceed 35℃, and the outlet water temperature should remain under 45℃.

    How should the induction heating capacitors be installed?

    Capacitors must be installed vertically (non-suspended) with a minimum space of 5 cm between each capacitor or other equipment, ensuring no excessive mechanical stress is placed on the terminals.
